Hmm - this is a tricky one :( One way might be to add
a Python script named 'PUT' to your ZClass, which calls
an alias that you could add to your subclass that calls
that right PUT. Non-optimal, but might do the trick.
<python script, arguments REQUEST, RESPONSE>
return self.my_PUT(REQUEST, RESPONSE)
def my_PUT(self, REQUEST, RESPONSE):
# new alias to call the right PUT. you could
# also just rename your custom PUT, but this
# example tries to preserve the contract of
# your base class in case something else
# depends on it...
return MyBaseClass.PUT(self, REQUEST, RESPONSE)
def PUT(self, REQUEST, RESPONSE):
# existing custom PUT handler
We were trying to make life easier for the majority by
adding FTP/DAV support to ZClasses, but as you point out
this may cause difficulties for folks who are trying to
handle certain HTTP methods themselves already :(
I wonder if a better way to go might be to provide a
mixin that people can use when defining a ZClass that
adds the default FTP/DAV support? Then I suppose that
people with existing ZClasses would then be mad (because
there would be no easy way to add that support to existing
